Given that usually the compiler does not complain about the coding style of a program (i.e. missing white spaces, indentation, long lines of code, name conventions, and comments), developers care only for the functionality of their programs and not for the maintainability. However, this can be harmful for the understanding and maintenance of modern software systems. This post discusses the importance of writing programs based on specific coding guidelines.
The last day of CHI in Seoul left everyone with that bittersweet taste of ending mixed with nostalgia and, was still a great day to see great research!
For me, the day started off with Augmented & Virtual Reality in the Real World (VR is here to stay!) and followed onto Interacting with Floors & Situated Displays (have you seen BaseLase? Check that video or the image below, quite an interesting approach to a portable large screen).
The last session of the CHI spectrum this year was Speech & Auditory Interfaces, which focused on lots of abstract sound UIs — really nice works there, go check it out if you are into sonic interaction. After this it was time for the closing keynote, by pop musician Psy. A local hero in mainstream Korea for obvious reasons and a humble speaker that decided to allude to his career build up and share lots of his personal insights with the HCI audience. At last, the next CHI was announced… see you all in San Jose for CHI’16!
Disclaimer: CHI is a multiple track conference, with a dozen of parallel sessions, so the truth is: I’ve never felt a bigger desire for ubiquity (the great thing is that this year things are being recorded and will be on the ACM Digital Library soon. Thanks to the SVs for filming the talks!)
In the third day of CHI a lot of attention was given to future interfaces that attach directly to the users’ body. The great thing is that being a research conference, CHI goes much further than the wearables and smartwatch industry so researches here presented developments in haptic wearables that control your muscles (an example of that is my own work presented this year), rings that notify you using temperature (Notiring), interactive tattoo-like stickers that allow you to interact directly onto your skin (iSkin), and even nail covers that allow you to secretly interact with your technology (NailO)!
Some future interfaces that live on your body: a bracelet that reads and writes to your muscles and a Nail interface:
Of course the CHI community is not only about new hardware but a much broader and grounded on the understanding of Computing and Human Factors. This means over the past three days we’ve seen many explorations and studies that provide a deeper understanding of the world of ergonomics, crowd-sourcing, collaborative work, interaction techniques, and human cognition too.
Furthermore, this year there has been an amazing body of work that takes the CHI community to the real world as discusses important, real-world questions, such as “Encouraging Energy Conservation”, “Gender inclusive Software” and a great focus (as always) in making HCI (and CHI) accessible to all people!
The second day of CHI started off quite happily for me as I was presenting my new work on Proprioceptive Interaction (sorry for shameful link!) at the muscle-interfaces session which was very interesting. In this session researchers discussed how future muscle sensing can be increased for higher resolution input or even by combining multiple technologies such as EMG and MMG. After that I could relax a bit and attend more interesting sessions on a variety of different topics! Later on, there were sessions on smartwatch interactions, which demonstrate that we are no longer in the smartwatch hype but instead we are really in the wearables era! Great to see that research are also thinking already beyond-wearables, skin interaction, smaller devices, haptic wearables and so forth, which will be presented tomorrow (Day 3, check the post too): looking forward to that!
Later on I attended a very interesting and futuristic session on 3D fabrication which in the same vein, demonstrates that we are beyond 3D printing only in the maker community but also in the HCI community! In this session researchers showed their new ideas for the world of fabrication, such as 3D printing using soft fabric (great for plushy-toys!), check their video here.
The day ended with the job fair… a great opportunity to the more junior people to find internships and perhaps a new position either at industry or research labs!
The first day of CHI started with a great opening plenary by Lou Yongqi (check keynotes here and yes, check out WHO is the closing plenary!), which came forward and highlighted the importance of Sustainability in research! Followed by an amazing program of novel technology (think Virtual Reality!), human augmentation (check this totally new way of embodying another person by Prof. Rekimoto), user studies (“Understanding and evaluating User Performance”), and understanding of elder users (“Designing for 55+”) and communities (a great session on Activism in Wikipedia, one on Privacy and one on the “Maker Community”)!
Also this was the day of the video-showcase, which is a non-academic venue in which authors can submit their videos for further appreciation. It is an amazing opportunity to great a glimpse of CHI by sitting in the theater and watching great research in motion. This year’s winner was the Transform project by the MIT Media Lab (see it here), from which one of the authors is our dear editor Sean Follmer, so congrats to him and his team!
